The steel orthotropic deck was used in the steel box girder of a suspension bridge. Four types of fatigue cracks were discovered at some connections of the orthotropic deck during service. Subsequently the pavement on the deck was replaced with epoxy asphalt concrete. To analyze the effect of the new pavement on the fatigue sensitive regions, a finite element model was established and field ...

Properties of Epoxy-Asphalt Pavement Mixture for Bridge Decks

Epoxy Asphalt Concrete (EAC) is a kind of high strength and flexible material thermosetting introducing epoxide resin and solidified agent into asphalt [2]. Characterizations of EAC refer to the ability of this material to satisfy the function of pavement on an orthotropic steel deck due to its special properties. EAC is a type of polymer concrete obtained by adding epoxy resins with a special ...

Three different epoxy asphalt binders were used and two pavement mix designs were employed. The binder and pavement mixture properties were evaluated by direct tensile and pull-off strength test on the binder, Marshall test of the paving mixture and flexural fatigue tests of paving mixture on steel plates. Test results show that a relatively high modulus binder and a relatively stiff pavement ...
